.UVVM file extension
To open .UVVM files on Windows, try opening the .uvvm file in a media player you already trust that can handle uncommon video types; if it fails, note any error message (unsupported codec/container, DRM/protection, etc.).
To open a .uvvm file, treat it as a DECE Mobile Video (MIME: video/vnd.dece.mobile) and first try opening it with a media player that supports uncommon MP4-like/packaged video variants. If it won’t play, the file may be part of a DECE/UltraViolet ecosystem workflow and not intended for direct playback outside a compatible implementation.

How to open .UVVM files
Use these platform-specific instructions to open .UVVM files safely.
Windows
- Try opening the .uvvm file in a media player you already trust that can handle uncommon video types; if it fails, note any error message (unsupported codec/container, DRM/protection, etc.).
- If the file came from a DECE/UltraViolet workflow, check whether you also received documentation or companion assets from the provider; the .uvvm may be intended to be handled by a DECE-compatible implementation rather than direct playback.
Mac
- Attempt to open the .uvvm in a media player that can try to play unknown file extensions; if it does not open, assume it requires DECE/UltraViolet-aware tooling.
- If this file was delivered as part of a streaming/download package, look for provider instructions—DECE media types are commonly used in managed device/streaming contexts.
Linux
- Open the file in a media player that can attempt playback based on file contents rather than extension; if it cannot parse it, it may be a DECE-profiled/managed video file.
- If you control the pipeline (developer/workflow scenario), ensure your tools treat the file as MIME type video/vnd.dece.mobile when mapping by extension.
iOS
- iOS apps typically key off common extensions and supported containers; if the file won’t import or play, transfer it to a desktop system and confirm whether it belongs to a DECE/UltraViolet workflow.
Android
- Try opening it with a player that can attempt playback of unknown extensions; if it fails, treat it as DECE/UltraViolet-associated content and use the provider’s intended app/workflow if available.
Security notes
- .uvvm is treated as a video vendor media type (video/vnd.dece.mobile). While it is not a script format, any complex media container can expose vulnerabilities in parsers/decoders; only open it in well-maintained media software.
- DECE/UltraViolet specifications are used in controlled distribution/streaming contexts; a .uvvm file obtained outside its original ecosystem may be incomplete (missing related assets/metadata) or not intended for standalone playback.
- If you operate a web service, ensure you serve .uvvm with the correct vendor MIME type (video/vnd.dece.mobile) where required by DECE workflows; incorrect content-type handling can lead to client-side misbehavior or failed playback/processing.
Can't open this file?
These are the most common causes and fixes when .UVVM files fail to open.
Common reasons
- The file won’t play in common media players
- Wrong content-type in a web/server context
- A tool renames or misclassifies the file
Fix steps
- Try a player that inspects file contents rather than relying on the extension; note whether the error is “unknown format” versus “codec not supported.”
- If the file originated from a DECE/UltraViolet delivery system, use the content provider’s intended workflow or request the same video in a more common packaging/extension.
Recover a deleted or lost .UVVM file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

OS-specific troubleshooting
What is a .UVVM file?
.uvvm is a filename extension used in DECE (Digital Entertainment Content Ecosystem) / UltraViolet profiles to indicate a “mobile” video variant, mapped by MIME databases to video/vnd.dece.mobile. The extension-to-MIME association is documented in multiple MIME mapping sources and referenced in DECE specifications for media types used in device/streaming contexts.
Background
The DECE/UltraViolet specifications define a family of vendor media types (video/vnd.dece.*) and associated filename extensions for content profiles and streaming usage. Within that ecosystem, .uvvm corresponds to the “mobile” video media type (video/vnd.dece.mobile), and appears in multiple MIME databases used by software stacks to infer content type from filenames.
In practice, users most often encounter .uvvm as a byproduct of DECE/UltraViolet packaging, delivery, or cataloging workflows rather than as a mainstream consumer video format. That means a .uvvm file may not behave like a typical “double-click to play” movie file even though it is categorized as video.
Because the sources primarily establish the MIME/type association (and not a specific consumer playback app), real-world usability depends on whether your player or workflow tools recognize DECE media type conventions. If you received a .uvvm file outside its original delivery system, you may need to request the content in a more common container/extension or obtain the correct DECE-compatible software from the content provider.
Common MIME types: video/vnd.dece.mobile

Common .UVVM issues
The file won’t play in common media players
.uvvm is associated with DECE Mobile Video (video/vnd.dece.mobile), which may not be recognized by consumer players purely by extension, or the content may be intended for a managed DECE/UltraViolet environment.
- Try a player that inspects file contents rather than relying on the extension; note whether the error is “unknown format” versus “codec not supported.”
- If the file originated from a DECE/UltraViolet delivery system, use the content provider’s intended workflow or request the same video in a more common packaging/extension.
Wrong content-type in a web/server context
Some servers and frameworks use extension-to-MIME mappings; if .uvvm isn’t mapped, it may be served with a generic MIME type, which can break clients expecting video/vnd.dece.mobile.
- Configure your server/application MIME mapping so .uvvm is served as video/vnd.dece.mobile.
- Verify the response headers and confirm the client expects DECE/UltraViolet vendor media types in the workflow.
A tool renames or misclassifies the file
Because .uvvm is rare, file managers and indexing tools may not know it, leading to incorrect labels or attempted opening with the wrong app.
- Check the file’s properties/details in your OS to confirm it is being treated as video/vnd.dece.mobile by your tooling where applicable.
- If you are building software that handles it, add an explicit mapping for .uvvm to video/vnd.dece.mobile using a MIME database as reference.
FAQ
What does .uvvm stand for?
In MIME databases and DECE-related references, .uvvm is associated with DECE Mobile Video and maps to the vendor MIME type video/vnd.dece.mobile.
Is there an official MIME type for .uvvm?
Yes. Multiple MIME mapping sources associate .uvvm with the vendor media type video/vnd.dece.mobile, and DECE specifications discuss vendor media types used for DECE/UltraViolet content profiles.
Can I safely rename .uvvm to .mp4 to make it play?
Renaming may help some apps attempt playback, but it does not convert the file. If the file relies on DECE/UltraViolet conventions or is not a plain MP4-compatible asset, renaming alone may not work.
Why do I see .uvvm in a server/project MIME mapping list?
Software stacks often ship extension-to-MIME maps; .uvvm appears in widely used MIME databases as video/vnd.dece.mobile, so projects include it to correctly label DECE mobile video content.
